First grow/stealth - need the experts

SO, this is day 34 of my first grow ever. It is mostly an experiment for this first try so the yield is not a huge concern, my main thing is to get everything at least 99% so the next grow will be perfect. Both of these plants sprouted on the 19th of october, i've had them under 24 hour lighting since (2, 42 watts cfls - 1 per plant). This is a stealth grow or , more so on the stealth side - the dimensions of the box are 24inches H, 20 inches L, and 14 inches W. I have 3, 80 MM case fans (2 in take, 1 exhaust) along with extra exhaust holes at the back. The room is covered in mylar top to bottom, I have a water jug that i put in there also to maintain humidity. When i had put the plants in the box was pretty dull, no fans no mylar not much just lights. I was having extreme humidity and temperature issues. (humidity like 10% and temp exceeding 120 f) after adjustments a few weeks later, i was looking at around 17% humidity and box temp at 98 f. a week or so later a few more adjustments , 92-94f and roughly 22-28% humidity. and now my final adjusments as you see in these pictures, my box temp is just steadying out right now , but its at around 88f and 35% humidity. Now for the plant side of things. I used only water up til a few days ago (Nov 19th) was my first nute day, and ive been altering watering with nutes 1 day, and just water the next ). As i know with all these temp and humidity jumps... my plants suffered serious trauma, also at the beginning i was watering every 2 days... so im sure i under watered them aswell. im almost positive the one is pretty dead since i havent seen real growth at all, the other one seems to be doin ALOT better from the pased 2 weeks grown 3 nodes ( since i started watering every single day at appx the same time every day) on the plant with actual leaves, the botom few leaves are yelow pale, and brown - but new growth seems to be good, and the nutes i started using are fox farm big bloom. the other plant, leaves are brown and green, and all the bottom ones died and fell off.. Although this is day 34 and still under 24 hour lighting ... my plants are no bigger than a average BIC lighter, even the one thats on its 5th node. NOW - for my thoughts, i know ive done things wrong, as i said this was my first grow ever. but im learning lots and every day i pay attention to detail as much as i can. this is mostly a hobby , but one i love and one id like to pursue in the future. so if i could have the experts advice on their thoughts, that would be great. im willing to invest a little more money - i have spent quite a bit on this bad boy , but some hobbies are expensive right!! If i have failed to mention anything - sorry and please feel free to ask!!! PS. I APOLOGIZE GREATLY FOR THE SHITTY QUALITY - saving money for a new camera (using webcam right now)

What soil are you using? Looks like there could be an issue there. I'd say that's more of a problem than the recent temperature swings. Cannabis can tolerate pretty crazy temps for short periods of time, especially in soil because the roots are more protected. Your pH could be off or there could be too many nutes already in the soil. If it were me, I'd flush the medium well and see how the plants respond. Plants that young under relatively weak lights (CFLs) don't need a whole lot of nutes until they've had a few weeks of vigorous growth, and even then you can go half strength just to be safe. If there are nutes already in the soil, I generally don't even fertilize until I see signs of deficiencies.

Blow some air across those babies. Don't water them too much - let them dry out a bit. One of them looks like shit. Not sure why. Hold off on any nutes. And keep your messages as short and to the point as possible. We'll help you 7lui.

It looks like a decent set up. What seeds are you growing? If they are bag seeds that set up is not likely going to work without transplanting them and using LST.

THAKS SO MUCH FOR REPLIES, okay - bass clef my soil is exactly premium nature mix by hortibec (all purpourse seed starting mix) the growing guy at the shop recomended it and my friend did as well!! he said its does have a little compost peat moss and perlite in it. and my buddy recomended the nutes because its been a month and they are FRIKEN TINY, (we both planted the same time and his are reaching a foot almost. plus the strain is great white shark ( from a very reliable source ) also, my water ph is exactly 7, toronto tap water is great for this!

also, bio wheel space is limited plus noise needs to be as queit as possible. as for the smell when time comes i have no worries with my ona gel, and its hidden in my closet so no worries of being seen. ! thanks!

it seems like something is wrong here bro. they shouldnt be yellowing like that on the bottom leaves and they should be much bigger if they are a month vegging, my plants are around a foot tall or more after a month, while you wont be able to do that well on your first grow they should def be bigger, i would have to say that the soil your using is bad for seedlings or maybe just bad for marijuana all around, do a little research, what type of soil are you using?

ak i had jsut posted that , read up ^ the soil was recomended to me. and i know for the height - my buddy has same strain and we planted same time his are approaching a foot but very different enviornments

I'd drop the ph to 6.5, plants like their water a little on the acidic side. Next thing I would do is get a good organic potting mix(fox farm ocean forest works wonders alone) then use nutrients specific for veg jacks classic 20-20-20 is cheap and works the best. I'd also highly reccomend transplanting to 3gallon pots at the most and switching your light to 12/12. Also hold back on the nutrients cuz that could be the problem on why the one looks dead. It's your first grow so don't get discouraged. Buy your seeds from a seed bank too next time cuz that's THE ONLY reliable source for good female seeds and you know exactly what your gonna get and they sometimes describe the ideal growing conditions for the strain. A great legit seedbank is attitudeseeds.com. Hope this helps.

I will try the ph thing for sure, and as for soil - pro mix is what we have in my area and that is best around here ( which i will try next ). for nutes i will look closely in to that.
as for 3 gallon pots.... my room is small, that wont fit - id need half gallon bags at the most. and switching to 12/12 would start flowering, i want to veg them a little longer ( an i started using the nutes (a quater table spoon per 250 ml ) 2 days ago, so today was actualy just the second time of using them. but i will take your word and leave them alone for now. for the seeds next time i will try ( i know the seeds are white shark 100%) wether they are feminen or not i do not know.

dont mess with your ph thats fine if its 7 the soil is a buffer and will buffer it down to where you need it

ok, any recomendations for the other problems?

to me it looks like heat may be the issue also should have added more perlite to your mix i would transplant asap into some new soil with added perlite no nutes till it recovers

right now my heat with my new changes is at 88.5 f and humidity at 32% . and im on my way to get some half gallon bags today and i will be starting with the pro mix soil, this has been a big problem and lots of trial and error since such a small place. im assuming i could add 1 more exhaust fan but that would be pretty maxed out for fan space, plus i feel transplanting in to the bigger pots would keep my humidity at a higher %

I would deff transplant into something a lil bigger and I agree with grorite, it really looks like heat is an issue and 88.5 in that little of space with no air blowing on them is just asking for trouble.

I wouldn't worry to much about a 32% humidity and if it raises a little bit that would work to your advantage as I like to grow with at least a 40% RH but have done it lower.

Ventilation is extremely important. Especially in that small of space.

That's always the problem with seeds. I have no doubt they are white shark but you could be growing all males and that would be a waste of time (unless you plan on breeding) which i would want a few successful grows Befor I tried breeding. Just do what you described and you should be good to go man

i think you really really need to get new soil to man, im betting thats ALOT of your problem.

giggles26 , i will be transplanting to half gallons for sure and i have fresh air coming in and leaving ( with the 2 intakes and 1 exhaust + exhaust holes ) so air is circulating, its not like its stale air, but i dont know how id fit an queit oscilating fan in there.. you know what im saying? im all ears i mean im now debating geting a 4th fan and puting it as exhaust where the holes lay. and wonderful cant wait for my humidity to raise! and, well thats why its all experimental for now cmbajr but i will look for feminen seeds in the future no question about that! and soil is coming aknight3!!!

any other FYI's from you experts? thanks for everything so far! lots of help!

to get the temps down a lil more freeze a few gals of water and put one in there it will help with your humidity and will cool it a bit should work good in that small space just make sure to put something under it to catch condensation
